Oh ok, I thought you meant pulling the eyeballs “inwards” as in towards the back of your head! What you describe, I’d normally call “crossing” my eyes.

Moving your eyes inwards

Details, please. 🤨

I just tried that and I can definitely say the closure happens at the pharynx for me, which is also what I do consciously when I hold my breath.

I am intimately familiar with that feeling. Because it’s not just popcorn that causes it. In apples, the seed chambers are lined with a hard membrane that is extremely similar in size and texture to a popcorn hull. If you bite too close to the core, or if you eat apple slices from uncored apples, youwill get one stuck in your throat.
